Raised Vs Flat Expanded Metal

Standard expanded metal sheets are passed through a cold roll reducing mill parallel to the diamond pattern lwd to form flattened expanded metal.

Raised vs flat expanded metal.

Common applications include walkways screens grills and safety guards. Expanded grating is milled in a similar manner to expanded metal. The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. Flattened expanded metal abbreviated f is manufa ctured by passing the metal through a cold roll reducing mill parallel to the lwd.

These raised strands can be flattened later in the process if desired. In many cases flattened expanded metal is a safer choice for these surfaces and is easier to clean. Hot rolled raised expanded metal sheets also referred to as grating or mesh is an excellent candidate for most processing techniques. There are standard expanded metal styles and numerous variations in strand width and opening sizes can be produced to create whatever architectural or industrial pattern is required.

Flat expanded metal sheets are lightweight carbon steel diamond shape openings with a raised surface for traction. Expanded metal sheet is made by first creating multiple slits in the sheet and then stretching the sheet. Expanded metal is also produced in a flattened form which is created by rolling standard or raised expanded metal. They are never a problem for me.

I keep them clean and well seasoned. By flattening the sheet the bonds and strands are turned down to produce a smooth and flat surface reducing the overall thickness and elongating the diamond pattern. Flattened expanded metal is what results when standard expanded metal is put through a cold rolling steel mill to flatten the expanded metal mesh out. This flattens the strands and bonds surface reducing the thickness gauge and elongating the pattern.

By flattening the sheet the bonds and strands are turned down to produce a smooth and flat surface essent ially elongating the lwd of the diamond. Standard expanded metal is often more useful for parts washing applications because the raised centers of the bonds prevent liquids from pooling in the basket. Otherwise you will have slivers of steel sticking up that will cause your meat to the grate and can also cause a nasty cut on your hands while handling them. My grates are 9 3 4 black carbon steel.

Be sure you get the flattened expanded metal. When considering construction type keep in mind that raised standard expanded metal will have rougher edges around the diamond that can tear meat and foil packs. In addition to food grates this product is particularly favored for charcoal. Flattened expanded metal is manufactured by passing the raised expanded sheet through a cold roll flattening press.

Flattened expanded metal on the other hand may be more useful for certain parts handling applications or for making larger custom mesh baskets slightly lighter by thinning out the.
